Finding Slope

Which of the following are ways to find the slope of a line?

• find the change in y over change in x

• find the rise over run

• find the difference in the y coordinates over difference in the x coordinates

• all of the above

What type of slope does the graph have?

• Zero slope

• Undefined slope

• Negative slope

• Positive slope

Find the slope

• -2/3

• 3/2

• -3/2

• 2/3

What is the slope?

• -4/3

• -3/4

• -2

• -6

Find the slope

• 4/5

• 5/4

• -5/4

• -4/5

What does this mean?

• the sum of the v-values over the sum of the x values

• run over rise

• change in y over change in x

• triangle y is similar to triangle x

What is the slope?

• -1/3

• -3

• -4

• 5

Calculate the slope of the line passing through the points (2, 3) and (5, 9).

• 10

• 5

• 2

• 3

Identify the slope and y-intercept of the equation y = 4x - 7.

• Slope = 7, Y-intercept = -4

• Slope = 4, Y-intercept = -7

• Slope = 4, Y-intercept = 7

• Slope = -7, Y-intercept = 4

Oliver and Anika are standing at two different points in a park. Oliver is standing at point (-1, 4) and Anika is standing at point (3, 10). If a line is drawn between these two points, calculate the slope of that line.
